| Publication Abstract: | We report on the first global QCD analysis of the quark transversity distributions in the nucleon from semi-inclusive deep-inelastic scattering (SIDIS), using a new Monte Carlo method based on nested sampling and constraints on the isovector tensor charge g_T from lattice QCD. A simultaneous fit to the available SIDIS Collins asymmetry data is compatible with g_T values extracted from a comprehensive reanalysis of existing lattice simulations, in contrast to previous analyses which found significantly smaller g_T values. The contributions to the nucleon tensor charge from u and d quarks are found to be \delta u = 0.3(2) and \delta d = -0.7(2) at a scale Q^2 = 2 GeV^2. |
